Indication(s)

1 INDICATIONS AND USAGE GENERESS Fe is indicated for use by women to prevent pregnancy. The efficacy of GENERESS Fe in women with a body mass index (BMI) of > 35 kg/m2 has not been evaluated. GENERESS Fe is an estrogen/progestin COC indicated for use by women to prevent pregnancy. (1) The efficacy in women with a body mass index (BMI) of > 35 kg/m2 has not been evaluated. (1, 8.8)

Usage information

2 DOSAGE AND ADMINISTRATION Chew one tablet without water at the same time every day. (2.1) Take tablets in the order directed on the blister pack. (2.1) 2.1 How to Take GENERESS Fe To achieve maximum contraceptive effectiveness, GENERESS Fe must be taken exactly as directed. Chew and swallow one tablet without water at the same time every day. Tablets must be taken in the order directed on the blister pack. Tablets should not be skipped or taken at intervals exceeding 24 hours. For patient instructions for missed pills, see FDA-Approved Patient Labeling. GENERESS Fe may be administered without regard to meals [see Clinical Pharmacology ( 12.3 )]. 2.2 How to Start GENERESS Fe Instruct the patient to begin taking GENERESS Fe on Day 1 of her menstrual cycle (that is, the first day of her menstrual bleeding). One light green tablet should be taken daily for 24 consecutive days followed by one brown tablet daily for 4 consecutive days [see FDA-Approved Patient Labeling ]. Instruct the patient to use a non-hormonal contraceptive as back-up during the first 7 days if she starts taking GENERESS Fe other than on the first day of her menstrual cycle. For postpartum women who do not breastfeed or after a second trimester abortion, GENERESS Fe may be started no earlier than 4 weeks postpartum. Recommend use of a non-hormonal back-up method for the first 7 days. When combined oral contraceptives (COCs) are used during the postpartum period, the increased risk of thromboembolic disease associated with the postpartum period must be considered. The possibility of ovulation and conception before starting COCs should also be considered. If the patient is switching from a combination hormonal method such as: - Another pill - Vaginal ring - Patch Instruct her to take the first light green pill on the day she would have started a new cycle of her previous birth control pack (Day 1). If she previously used a vaginal ring or transdermal patch, she should start using GENERESS Fe on the day she would have restarted the ring or patch. Instruct the patient to use a non-hormonal back-up method such as a condom and spermicide for the first 7 days. If the patient is switching from a progestin-only method such as: - Progestin-only pill - Implant - Intrauterine system - Injection Instruct her to take the first light green pill on the day she would have taken her next progestin-only pill or on the day of removal of her implant or intrauterine system or on the day when she would have had her next injection. Instruct the patient to use a non-hormonal back-up method such as a condom and spermicide for the first 7 days. 2.3 Advice in Case of Gastrointestinal Disturbances In case of severe vomiting or diarrhea, absorption may not be complete and additional contraceptive measures should be taken. If vomiting or diarrhea occurs within 3-4 hours after taking a light green tablet, this can be regarded as a missed tablet [see FDA-Approved Patient Labeling ].

8 USE IN SPECIFIC POPULATIONS Nursing mothers: Not recommended, can decrease milk production. (8.3) 8.1 Pregnancy There is little or no increased risk of birth defects in women who inadvertently use COCs during early pregnancy. Epidemiologic studies and meta-analyses have not found an increased risk of genital or non-genital birth defects (including cardiac anomalies and limb-reduction defects) following exposure to low dose COCs prior to conception or during early pregnancy. The administration of COCs to induce withdrawal bleeding should not be used as a test for pregnancy. COCs should not be used during pregnancy to treat threatened or habitual abortion. Women who do not breastfeed may start COCs no earlier than four weeks postpartum. 8.3 Nursing Mothers When possible, advise the nursing mother to use other forms of contraception until she has weaned her child. Estrogen-containing OCs can reduce milk production in breastfeeding mothers. This is less likely to occur once breastfeeding is well-established; however, it can occur at any time in some women. Small amounts of oral contraceptive steroids and/or metabolites are present in breast milk. 8.4 Pediatric Use Safety and efficacy of GENERESS Fe have been established in women of reproductive age. Efficacy is expected to be the same in postpubertal adolescents under the age of 18 years as for users 18 years and older. Use of this product before menarche is not indicated. 8.5 Geriatric Use GENERESS Fe has not been studied in postmenopausal women and is not indicated in this population. 8.6 Renal Impairment The pharmacokinetics of GENERESS Fe have not been studied in subjects with renal impairment. 8.7 Hepatic Impairment No studies have been conducted to evaluate the effect of hepatic disease on the disposition of GENERESS Fe. However, steroid hormones may be poorly metabolized in patients with impaired liver function. Acute or chronic disturbances of liver function may necessitate the discontinuation of COC use until markers of liver function return to normal [see Contraindications ( 4 ), and Warnings and Precautions ( 5.3 )] . 8.8 Body Mass Index The safety and efficacy of GENERESS Fe in women with a BMI > 35 kg/m2 have not been evaluated.

8.3 Nursing Mothers When possible, advise the nursing mother to use other forms of contraception until she has weaned her child. Estrogen-containing OCs can reduce milk production in breastfeeding mothers. This is less likely to occur once breastfeeding is well-established; however, it can occur at any time in some women. Small amounts of oral contraceptive steroids and/or metabolites are present in breast milk.

Interactions

7 DRUG INTERACTIONS No drug-drug interaction studies were conducted with GENERESS Fe. Drugs or herbal products that induce certain enzymes, including CYP3A4, may decrease the effectiveness of COCs or increase breakthrough bleeding. Counsel patients to use a back-up method or alternative method of contraception when enzyme inducers are used with COCs. (7.1) 7.1 Changes in Contraceptive Effectiveness Associated with Co-Administration of Other Products If a woman on hormonal contraceptives takes a drug or herbal product that induces enzymes, including CYP3A4, that metabolize contraceptive hormones, counsel her to use additional contraception or a different method of contraception. Drugs or herbal products that induce such enzymes may decrease the plasma concentrations of contraceptive hormones, and may decrease the effectiveness of hormonal contraceptives or increase breakthrough bleeding. Some drugs or herbal products that may decrease the effectiveness of hormonal contraceptives include: barbiturates bosentan carbamazepine felbamate griseofulvin oxcarbazepine phenytoin rifampin St. John’s wort topiramate HIV protease inhibitors and non-nucleoside reverse transcriptase inhibitors: Significant changes (increase or decrease) in the plasma levels of the estrogen and progestin have been noted in some cases of co-administration of HIV protease inhibitors or with non-nucleoside reverse transcriptase inhibitors. Antibiotics: There have been reports of pregnancy while taking hormonal contraceptives and antibiotics, but clinical pharmacokinetic studies have not shown consistent effects of antibiotics on plasma concentrations of synthetic steroids. Consult the labeling of all concurrently-used drugs to obtain further information about interactions with hormonal contraceptives or the potential for enzyme alterations. 7.2 Increase in Plasma Levels of Ethinyl Estradiol Associated with Co-Administered Drugs Co-administration of atorvastatin and certain combination oral contraceptives containing ethinyl estradiol increase AUC values for ethinyl estradiol by approximately 20%. Ascorbic acid and acetaminophen may increase plasma ethinyl estradiol levels, possibly by inhibition of conjugation. CYP3A4 inhibitors such as itraconazole or ketoconazole may increase plasma hormone levels. 7.3 Concomitant Use with HCV Combination Therapy – Liver Enzyme Elevation Do not co-administer GENERESS Fe with HCV drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, due to potential for ALT elevations [see Warnings and Precautions ( 5.4 )]. 7. 4 Changes in Plasma Levels of Co-Administered Drugs COCs containing some synthetic estrogens (e.g., ethinyl estradiol) may inhibit the metabolism of other compounds. COCs have been shown to significantly decrease plasma concentrations of lamotrigine, likely due to induction of lamotrigine glucuronidation. This may reduce seizure control; therefore, dosage adjustments of lamotrigine may be necessary. Consult the labeling of the concurrently-used drug to obtain further information about interactions with COCs or the potential for enzyme alterations.
